1. 3032
2. 3036
3. 3040
4. 3028

Answer 1

Correct Answer - Option 2 : 3036

Given: 

Bank	Candidates Appearing	% of Candidates Qualifying
I	2200	26
J	3000	17

Calculation:

Bank	Candidates Appearing	% of Candidates Qualifying	Number of candidates who qualified	Number of candidates who did not qualify
I	2200	26	2200 × 26% = 572	2200 - 572 = 1628
J	3000	17	3000 × 17% = 510	3000 - 510 = 2490

Number of candidates who did not qualify in banks I and J together = 1628 + 2490 = 4118
Number of candidates who qualified in banks I and J together = 572 + 510 = 1082

Required difference = 4118 - 1082 = 3036

∴ Required difference is 3036.
